ROLLER-BEARING.

Application flied March 13. 1918.

['0 all whom it may oncern.

Be it known that I. Geouoa W Coxuow, citizen of the United States, residing at Brooklyn, in the county of Kings and State of New York, have invented a certain new and useful Im rov'ement in Roller-Bearings,: of which the following is a full. clear. concise, and exact description.

My invention relates to roller bearing structures and includes an improved formation of the cages by means of which bearingh'roll'ers are assembled. In accordance wi 'one feature'of my invention the'roll'er assembling cage of a roller bearing structure is formed with flanges that are joined byribsz The'flanges and the bearing rollers have 'interengaging formations for assemblingthe flanges and the rollers while the ri'bsintervene between said bearing rollers. At'leasti one of the flanges is formed in pot tions that are relatively movable across the general plane of such flan e whereby rollers may be assembled with di ring portions 'of this flange-without disturbing-the assembly ofother'r'ollers with suclr flange.

In the preferred embodiment of the invention 'eachflange has roller engaging portions-that are each individual to a roller and w-hich'portions are relatively movable transversely ofthe general planes of the flanges. In accordance with another feature of the invention the flanges are integrally-forinedwitli the ribs out of spring me'tal-suchas spring steel, a construction which moreover'simplifies the manufacture of bearin roller cages and the assembly thereof with hearing rollers.

[will explain my invention more fully byrefi'en'ceto the accom anying drawing showing the preferred embodiment thereof and in which Figure 1 is a view taken on line-1 1 of Fig. -'2;Fig. 2 is a view taken on line 2-2 of Fig. 1: Fig. 3 is a per spective view illustrating the preferred formation of a cylindrical cage for bearing rollers; Fig. 4 is a longitudinal sectional view of the cage shown in Fig. 3. this figure illustrating the manner of assembling bearing rollers with the cage: Fig. 5 is a view on line 5-5 of Fig. 6, illustrating some modification; and Fig. 6 is a view on line 66 of Fig. 5.

Like parts are indicated by similar char actors of refcreuvc throughout the difl'erent figures.

The roller bearing structure illustrated is Specification of Letters Patent.

one which includes a cage that is cylindrical but it is obvious that the invention is not to be limited to any particular shape of thc cage nor to the shape of the bearing rollers which, in the form of the invention illustrated-are also cylindrical with conical ends.

The ribs 1 are extended longitudinally of the bearing structure joining the flanges 2. As illustrated, the ribs are connected with the flanges at the inner circles of the flanges. to whi'c" construction I do not wish to be limited. The flanges and the ribs are desira'bly integrallv formed of sprin metal suclr'as steel. ach flange prefera ly includes roller engaging portions 3 that are relatively movable transversely or across the general planes of the flanges, each of those portions 3 being capable of being flexed across its normal plane without disturbing its neighbors whereby each bearing roller 4 may be assembled with flanges between which it is to be interposed without disturbing theother rollers which may have been previously assembled witli'the flanges. The

earingi'rollers 4 that are illustrated have outwardly projecting conical ends 4 on which accounteach'of the roller engaging parts 3 of each flange are outwardly dished to correspond generally with the formation of the ends of the rollers. The rollers are desirably of such a length that they are loosely held but not dis odgeable without outwardly flexing the roller engaging flange parts 3. The roller engaging flange parts 3 are desirably provided with apertures 5 at their apices for the free accommodation ofthe apices of the bearing rollers and for the passage of lubricating oil if the rollers are to be immersed in lubricant.

In the preferred embodiment of the invention the ends of the ribs '1 terminate at the planes of the flanges whereby it is un' nece$ary to form the rollers with shouldered portions at their ends, it being pos sible for the rollers. throu hout their cylindrical lengths. to project t rough the spaces between the ribs into engagement with the element which is to be supported by the bearing.

In each embodiment of the in vention illus trated I have shown a shaft 6 which is en gagexi by the portions of the rollers 4 that. inwardly project through the spaces between the ribs 1. The outward portions of the bearing rollers. in the construction shown in Figs. 1 and '2. engage the cylindrical wall 7 formed in the bearing box or pedestal 8. In the embodiment. of the invention shown in Figs. 5 and 6, a housing 9 is disposed within the bore 1.0 of the bearing box or pedestal, the outer parts of the rollers engaging this housing instead of engaging the wall of the bore 10 directly. This housing has an inwardly projecting end wall 9 integrally formed therewith, there being a washer 11 held in place at the other end of the housing by means of the bead 12. The housing 9 is rigidly assembled with the hearing pedestal that incloses it whereby the general plane of bodily movement and individual rotation of the rollers is defined. In the construction illustrated in Figs. l and 2 and in the construction illustrated in Figs. 5 and 6 the cages and the bearing rollers assembled therewith are together capable of slight bodily movement longitudinally of the shaft 6.

While I have herein shown and particularly described the preferred embodiments of my invention I do not wish to be limited to the precise details of construction shown as changes may readily be made without departing from the spirit. of my invention, but

Having thus described my invention I claim as new and desire to secure by Letters Patent the following A 1. A roller bearing structure including a cage comprising ribs and flanges joined by the ribs; and bearin rollers between which said ribs are disposed, said flanges andthe ends of said rollers having interengaging formations for assembling the flanges and rollers, at least one of said flanges havin roller engaging portions that are each in ividual to a roller and arerelatively movable across the general plane 'of such flange.-

2. A roller bearing structure'includingba cage comprising ribs and flanges joined the ribs; and bearing rollers'between which said ribs are disposed said flanges and, the ends of said rollers 'aving interengaging formations for assembling the flanges an rollers, at least one of said flanges being made of spring metal and having roller en- Gc'ples of this patent may be obtained for gaging portions lhnt are each individual to a roller and are relatively movable across the general plane of such flange.

3. A roller bearing structure including a cage comprising ribs and flanges joined by and integrally formed with the ribs; and bearing rollers between which said ribs are disposed, said flanges and the ends of said rollers havin interengaging formations for assembling t c flanges and rollers, at least one of said flanges having roller engaging portions that are relatively movable across the general plane of such flange.

4. A roller bearing structure including a cage comprising ribs and flanges joined by and integrally formed with the ribs; and bearing rollers between which said ribs are disposed, said flanges and the ends of said rollers havin interengaging formations for assembling t e flanges and rollers, at least one of said flanges having roller engaging portions that are each individual to a roller and are relatively movable across the general plane of such flange.

5. A roller bearing structure including a cage comprising ribs and flanges joined by and integrally formed with the ribs of spring metaland bearing rollers between which said ribs are disposed, said-flanges and the ends of said rollers havin interengagingformations for assemb in v the flanges and rollers, at least one 0 said flanges having roller engaging portions that are relativel movable across the general plane of sue flange.

6. A roller bearing structure including a cage comprising ribs and flanges of spring metal joined by and into 11y formed with the ribs; and bearing roll said ribs are di. osed, said flanges and the ends of said rolers having interengagin formations for amembling the-flanges-an rollers, at least one of said flanges'having roller engaging portions that are dividual to a roller and are relatively movable across the eneral plane of such'flan In witness w ereof, I hereunto subscri de 6th day of March, A; 13.51918;
